Which object is vibrating when the following sounds are produced?
(i) The sound of a sitar
(ii) The sound of a tabla
(iii) The sound of a tuning fork
(iv) The buzzing of a bee or mosquito

Fill in the blank with suitable word.
When the frequency of the sound is increased, the wavelength ____________.
Draw the sketches of two waves A and B such that wave A has twice the wavelength and half the amplitude of wave B.
A sound producing body is at considerable distance from a man. There can be four different media W, X, Y and Z between the sound producing body and the man. The medium X brings the sound to man most quickly whereas medium Z takes the maximum time. The time taken by medium W in bringing sound to man is less than that of X but more than that of Z. The medium Y, however, fails to bring the sound from the sound producing body to the man. Which medium could be the one :
(a) having on fixed shape and no fixed volume?
(b) having a fixed volume but no fixed shape?
(c) having the same composition as that on the moon?
(d) having a fixed shape and a fixed volume?

Match the following:
| Human larynx | Vibrations of metal arms |
| Loudspeaker | Vibrations in air column |
| Jal-Tarang | Vibrations in vocal cords |
